a light beam shines through a slit and illuminates a distant screen. The central bright fringe on the screen is 1.00 cm wide, as measured between the dark fringes that border it on either side. Which of the following actions would decrease the width of the central fringe? ( There may be more than one correct answer) a- increase the wavelength of the light b-decrease the wavelength of the light c-increase the width of the slit d-put the apparatus all...
In a single-st experiment 480 nm Ight illuminates a 0.15mm wide sit. A diffraction pattern is observed on a screen 2.5 m away from the sit. How wide is the central bright fringe observed on the screen? Sube
(d) (8 marks) An aperture in the form of a narrow slit 0.28 mm wide forms a diffraction pattern on a screen placed 7.0 m away when illuminated with light of wavelength 600 nm. (1) Calculate the width of the central peak of the diffraction pattern (i.e. from minimum to minimum) on the screen. (11) If instead of using one slit the light illuminates two such slits separated by 0.90 mm, what is the separation of the interference maxima formed...
3. When a monochromatic light source shines through a 1 mm wide slit onto a screen 7 m away, the first dark band in the pattern appears 4 mm from the center of the bright band. What is the wavelength of the light? What color is it? If instead of a single slit, you had two slits separated by 1 mm, what would you see?
A helium-neon laser (λ=633nm) illuminates a diffraction grating. The distance between the two m=1 bright fringes is 36 cm on a screen 1.7 m behind the grating. What is the spacing between slits of the grating?
A helium-neon laser (λ=633nm) illuminates a diffraction grating. The distance between the two m=1 bright fringes is 32 cm on a screen 2.3 m behind the grating. What is the spacing between slits of the grating?
A helium-neon laser (λ=633nm) illuminates a diffraction grating. The distance between the two m=1 bright fringes is 37 cm on a screen 1.8 m behind the grating. What is the spacing between slits of the grating?
A student performs a double-slit experiment using a monochromatic light source with a wavelength of 5.00 ´ 10–7 m. The pattern appears on a screen 150 cm away and the bright fringes are 0.40 cm apart. If the wavelength of the light used is changed to 7.50 ´ 10–7 m, what would the average distance between bright fringes become? a. 0.15 cm d. 0.60 cm b. 0.20 cm e. 1.5 m c. 0.27 cm
2. When light with a wavelength of 675 nm is shined through two closely spaced slits and projected onto a screen that is 0.8 m away, the first minimum on the left of the center is 5.4 cm from the first maximum on the right. (a) How far apart are the two slits? (b) How wide are the low-order bright fringes? cm (c) At what angles do the first minimum and first maximum occur? 01min 2. When light with a...
